In this quest you have to retrieve Fragments of Wuuthrad at Dustman’s Cairn.

The main difficulties that you will run into at Dustman’s Cairn is large groups of enemies. When you are facing large groups of enemies it is best to always kill the weaker enemies first and then start on the stronger ones. Also be sure to maneuver in such a way that you can only ever be hit by one enemy at a time. The best way to do this is to thunnel them through small caverns or lead them around large stones or other obstacles.

At a particular point you will be locked inside a small cave without a way out. Don’t worry, eventually Farkas will let you out.

Once you have collected the fragments of Wuuthrad you can leave this dungeon. However, I decided to stay. You will be in a lot of trouble because around 20 to 30 enemies in total will spawn at about 3 or 4 a time. Use the tactics I described earlier to deal with these groups of enemies.
